  • TEMPERATURE SENSOR AND HYDROGEN-FILLED SYSTEM
    Publication number: 20130077653
    Abstract: A temperature sensor excellent in durability under a high-pressure atmosphere of hydrogen is provided. The temperature sensor includes a thermistor element body comprising an oxide sintered body, a pair of lead wires each electrically connected to the element body and comprising Pt or a Pt alloy, and a sealing glass sealing the element body and a part of the lead wires including a portion connected to the element body. The pair of lead wires comprising any of Pt, an alloy comprising Pt and one or two of Ir and Pd, and an alloy of Pd and Ir, and the temperature sensor is used under an atmosphere of hydrogen.

  • Temperature sensor and production method thereof
    Patent number: 6880969
    Abstract: In a temperature sensor including a pair of electrode wires for signal lead-out, bonded to both opposing end faces of a thermistor device, this invention aims at preventing peeling, of bond portions, between the electrode wires and the thermistor device. This object can be accomplished by sealing the thermistor device 3 and the bond portions between the thermistor device 3 and the electrode wires 4 by using an electrically insulating glass member 6, and holding the pair of electrode wires 4 by using a holding member 8 made of an electrically insulating ceramic while a gap is kept between them.
